Question

我有一个问题：我必须在之间提取文本＆＃34;主体＆＃34; {＆＃34;文本＆＃34;：＆＃34; 和＆＃34;＆＃34 ;. 在这个例子中发生了2次，这些是来自Facebook的评论。我想从两个标准之间提取和放置文本到单个变量，由换行符分隔。我使用PHP，已经在名为$ html的变量中获得了整个HTML。

以下是代码：

[
   {
      "id":"537891442938686_1601777",
      "fbid":"537891612938669",

      "body":{
         "text":"Jaaa:D",
         "ranges":[

         ],
         "aggregatedranges":[

         ]
      },

         "verbose":"4. junij 2013 ob 22:54"
      },
      "spamreplycount":0,
      "replyauthors":[

      ],
      "isfeatured":false
   },
   {
      "id":"537891442938686_1601790",

您所拥有的数据采用JSon格式。我强烈建议解码并将其放入对象中。之后，您可以轻松地遍历所需的所有属性。看看json_decode（http://php.net/manual/en/function.json-decode.php）。

使用php从html / javascript中将文本提取到字符串中
